Abstract

A touch display device is provided. The touch display device comprises a first substrate, a second substrate opposite to the first substrate, a display medium layer, a cover layer, and a first touch electrode layer disposed between the first substrate and the cover layer. The second substrate is disposed between the cover layer and the first substrate. The thickness of the first touch electrode layer is between (1400 Å×N)×1.1 and (1400 Å×N)×0.9, where N is one of a positive integer of 1 to 5.
